Many thanks for responding. Waiting on MAC code from o2 - coming by e-mail. Spoke with chap from BT about 40Gb usage and he tells me that if (dont think I will) I exceed 40Gb in the first month they do not charge. After that its £5 for every 5Gb exceeded.
Will be able to keep an eye on it.
Silly I know, but quite excited at getting higher speeds. I've been on 2.4 download for ages now. Fastest was 2.8. Infinity are quoting 23.7. Yes, yes, yes.
The only thing to watch out for is multiple users... When my daughter was at home, her iPlayer habit together with her mum's, plus my daughter being incessantly on YouTube, plus goodness knows what other streaming, plus my son's gaming (most of them downloaded) plus other daughter being home from college meant that we regularly used in excess of 100GB/month. Thank goodness for PlusNet's truly unlimited service - which, sadly, I believe they no longer offer.
